CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Cautionary Note Regarding Forward-Looking Statements

In addition to historical information, this Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995. Forward-looking statements are those that predict or describe future events or trends and that do not relate solely to historical matters. You can generally identify forward-looking statements as statements containing the words "believe," "expect," "will," "anticipate," "intend," "estimate," "project," "assume" or other similar expressions, although not all forward-looking statements contain these identifying words. Forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from historical experience or the Company’s present expectations. Some of the things that could cause actual results to differ from our expectations are:


•	the competitive environment in our industry;


•	changes in our operating costs, including fuel, which can be volatile;


•	our ability to meet our cost reduction goals;


•	our ability to achieve anticipated synergies and timing thereof in connection with our acquisition of Virgin America;


•	our ability to successfully integrate the Boeing and Airbus operations into those of Alaska;


•	labor disputes and our ability to attract and retain qualified personnel;


•	operational disruptions;


•	general economic conditions, including the impact of those conditions on customer travel behavior;


•	the concentration of our revenue from a few key markets;


•	an aircraft accident or incident;


•	actual or threatened terrorist attacks, global instability and potential U.S. military actions or activities;


•	our reliance on automated systems and the risks associated with changes made to those systems;


•	changes in laws and regulations.

You should not place undue reliance on our forward-looking statements because the matters they describe are subject to known and unknown risks, uncertainties and other unpredictable factors, many of which are beyond our control. Our forward-looking statements are based on the information currently available to us and speak only as of the date on which this report was filed with the SEC. We expressly disclaim any obligation to issue any updates or revisions to our forward-looking statements, even if subsequent events cause our expectations to change regarding the matters discussed in those statements. Over time, our actual results, performance or achievements will likely differ from the anticipated results, performance or achievements that are expressed or implied by our forward-looking statements, and such differences might be significant and materially adverse to our shareholders. For a discussion of these and other risk factors, see Item 1A. "Risk Factors” of the Company’s annual report on Form 10-K for the year ended December 31, 2017, and Item 1A. "Risk Factors" included herein. Please consider our forward-looking statements in light of those risks as you read this report.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

NOTE 1. GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization and Basis of Presentation

The condensed consolidated financial statements include the accounts of Air Group, or the Company, and its primary subsidiaries, Alaska (including Virgin America) and Horizon. Our condensed consolidated financial statements also include McGee Air Services, a ground services subsidiary of Alaska. The Company conducts substantially all of its operations through these subsidiaries. All significant intercompany balances and transactions have been eliminated. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information. Consistent with these requirements, this Form 10-Q does not include all the information required by GAAP for complete financial statements. It should be read in conjunction with the consolidated financial statements and accompanying notes in the Form 10-K for the year ended December 31, 2017. In the opinion of management, all adjustments have been made that are necessary to fairly present the Company’s financial position as of June 30, 2018 and the results of operations for the three and six months ended June 30, 2018 and 2017. Such adjustments were of a normal recurring nature.

Certain reclassifications have been made to prior year financial statements to conform to classifications used in the current year.

In preparing these statements, the Company is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities, as well as the reported amounts of revenues and expenses. Due to seasonal variations in the demand for air travel, the volatility of aircraft fuel prices, changes in global economic conditions, changes in the competitive environment and other factors, operating results for the three and six months ended June 30, 2018 are not necessarily indicative of operating results for the entire year.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)," which requires lessees to recognize assets and liabilities for leases currently classified as operating leases. Under the new standard, a lessee will recognize a liability on the balance sheet representing the lease payments owed, and a right-of-use-asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election not to recognize lease assets and lease liabilities.

In July 2018, the FASB issued ASU 2018-11, "Targeted Improvements - Leases (Topic 842)" which amended Topic 842 to provide companies an alternative transition method which would not require adjusting comparative period financial information. The Company plans to utilize this alternative transition method. The new standard is effective for the Company on January 1, 2019. The Company will not early adopt the standard.

At this time, the Company believes the most significant impact to the financial statements will relate to the recording of a right-of-use-asset and related liability associated with leased aircraft. The Company does not expect the new standard to have a material impact on the pattern or amount of expense recognized for aircraft leases on the income statement. Other leases, including airports and real estate, equipment, software and other miscellaneous leases continue to be assessed.

In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows—Restricted Cash (Topic 230)" related to the presentation of restricted cash on the statement of cash flows, and within the accompanying footnotes. The Company adopted the standard effective January 1, 2018.

In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." The ASU expands the activities that qualify for hedge accounting and simplifies the rules for reporting hedging relationships. The ASU is effective for the Company beginning January 1, 2019. The Company will not early adopt the standard.

In February 2018, the FASB issued ASU 2018-02, "Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." The standard allows a reclassification from accumulated other comprehensive income (AOCI) to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The amount of the reclassification is the difference between the amount initially recorded directly to other comprehensive income at the previously enacted U.S. federal corporate income tax rate that remains in AOCI and the amount that would have been recorded directly to other comprehensive income using the newly enacted U.S. federal

income tax rate. The standard is effective for interim and annual reporting periods beginning after December 15, 2018, and early adoption is permitted. The Company elected to early adopt the standard effective January 1, 2018. As a result, retained earnings increased approximately $62 million in 2018 due to the reclassification of tax effects in AOCI recorded in prior periods at previously enacted tax rates.

NOTE 2. RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

Revenue Recognition and Retirement Benefits Accounting Standards

In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)." The Company adopted the new standard as of January 1, 2018, utilizing a full retrospective transition method. Adoption of the new standard resulted in changes to accounting policies for revenue recognition related to frequent flyer activity, certain ancillary revenues such as change fees, air traffic liabilities, and sales and marketing expenses. As a result of adoption, the Company also changed certain financial statement line item disclosure captions. See Note 3 for a discussion of the impact of this standard.

Although less significant, in March 2017 the FASB issued ASU 2017-07, "Compensation - Retirement Benefits (Topic 715)," which requires the Company to present the service cost component of net periodic benefit cost as Wages and benefits in the statement of operations. The Company adopted the new standard as of January 1, 2018, utilizing a full retrospective transition method. Under this new standard, all components of net periodic benefit cost are presented in Nonoperating income (expense), except service cost, which remains in Wages and benefits.

Certain line item captions on the balance sheet and statement of operations changed as a result of the newly implemented standards. Accordingly, historical financial information presented below as reported has been presented using the new captions. The cumulative impact to retained earnings at January 1, 2016 as a result of the new revenue recognition standard was $171 million. Below are the impacts of these newly adopted accounting standards to the financial statements.

NOTE 3. REVENUE

Ticket revenue is recorded as Passenger revenue, and represents the primary source of the Company's revenue. Also included in Passenger revenue are passenger ancillary revenues such as bag fees, on-board food and beverage, ticket change fees, and certain revenue from the frequent flyer program. Mileage Plan™ other revenue includes brand and marketing revenue from our co-branded credit card and other partners and certain interline frequent flyer revenue, net of commissions. Cargo and other revenue includes freight and mail revenue, and to a lesser extent, other ancillary revenue products such as lounge membership and certain commissions.

The Company disaggregates revenue by segment in Note 9. The level of detail within the Company’s statements of operations, segment disclosures, and in this footnote depict the nature, amount, timing and uncertainty of revenue and how cash flows are affected by economic and other factors.

Passenger Ticket and Ancillary Services Revenue

The primary performance obligation on a typical passenger ticket is to provide air travel to the Company’s passenger. Ticket revenue is collected in advance of travel and recorded as Air Traffic Liability (ATL) on the consolidated balance sheets. The Company satisfies its performance obligation and recognizes ticket revenue on each flight segment when the transportation is provided.

Ancillary passenger revenues relate to items such as checked-bag fees, ticket change fees, and on-board food and beverage sales, all of which are provided at time of flight. As such, the obligation to perform these services is satisfied at the time of travel and is recorded with ticket revenue in Passenger revenue.

Revenue is also recognized for tickets that are expected to expire unused, a concept referred to as “passenger ticket breakage.” Passenger ticket breakage is recorded at the flight date using estimates made at the time of sale based on the Company’s historical experience of expired tickets, and other facts such as program changes and modifications.

In addition to selling tickets on its own marketed flights, the Company has interline agreements with partner airlines under which it sells multi-city tickets with one or more segments of the trip flown by a partner airline, or it operates a connecting flight sold by a partner airline. Each segment in a connecting flight represents a separate performance obligation. Revenue on segments sold and operated by the Company is recognized as Passenger revenue in the gross amount of the allocated ticket price when the travel occurs, while the commission paid to the partner airline is recognized as a selling expense when the related transportation is provided. Revenue on segments operated by a partner airline is deferred for the full amount of the consideration received at the time the ticket is sold and, once the segment has been flown the Company records the net amount, after compensating the partner airline, as Cargo and other revenue.

A portion of revenue from the Mileage Plan™ program is recorded in Passenger revenue. As members are awarded mileage credits on flown tickets, these credits become a distinct performance obligation to the Company. The Company allocates the transaction price to each performance obligation identified in a passenger ticket contract on a relative standalone selling price basis. The standalone selling price for loyalty mileage credits issued is discussed in the Loyalty Mileage Credits section of this Note below. The amount allocated to the mileage credits is deferred on the balance sheet. Once a member travels using a travel award redeemed with mileage credits on one of the Company's airline carriers, the revenue associated with those mileage credits is recorded as Passenger revenue.

Taxes collected from passengers, including transportation excise taxes, airport and security fees and other fees, are recorded on a net basis within passenger revenue in the consolidated statements of operations.

As passenger tickets and related ancillary services are primarily sold via credit cards, certain amounts due from credit card processors are recorded as airline traffic receivables. These credit card receivables and receivables from our affinity credit card partner represent the majority of the receivables balance on the Balance Sheet.

For performance obligations with performance periods of less than one year, GAAP provides a practical expedient that allows the Company not to disclose the transaction price allocated to remaining performance obligations and the timing of related revenue recognition. As passenger tickets expire one year from ticketing, if unused or not exchanged, the Company elected to apply this practical expedient.

Mileage Plan™ Loyalty Program

Loyalty mileage credits

The Company’s Mileage Plan™ loyalty program provides frequent flyer travel awards to program members based upon accumulated loyalty mileage credits. Mileage credits are earned through travel, purchases using the Mileage Plan™ co-branded credit card and purchases from other participating partners. The program has a 24-month expiration period for unused mileage credits from the month of last account activity. The Company offers redemption of mileage credits through free, discounted or upgraded air travel on Alaska flights or on one of its 16 airline partners, as well as redemption at partner hotels.

The Company uses a relative standalone selling price allocation to allocate consideration to material performance obligations in contracts with customers that include loyalty mileage credits. As directly observable selling prices for mileage credits are not available, the Company determines the standalone selling price of mileage credits primarily using actual ticket purchase prices for similar tickets flown, adjusted for the likelihood of redemption, or breakage. In determining similar tickets flown,

the Company considers current market prices, class of service, type of award, and other factors. For mileage credits accumulated through travel on partner airlines, the Company uses actual consideration received from the partners.

Revenue related to air transportation is deferred in the amount of the relative standalone selling price allocated to the loyalty mileage credits as they are issued. The Company satisfies its performance obligation when the mileage credits are redeemed and the related air transportation is delivered.

The Company estimates breakage for the portion of loyalty mileage credits not expected to be redeemed using a statistical analysis of historical data, including actual mileage credits expiring, slow-moving and low-credit accounts, among other factors. The breakage rate for the three and six months ended June 30, 2018 and 2017 was 17.4%. The Company reviews the breakage rate used on an annual basis.

Co-brand credit card agreement and other

In addition to mileage credits, the co-brand credit card agreement, referred to herein as the Agreement, also includes performance obligations for waived bag fees, Companion Fare™ offers to purchase an additional ticket at a discount, marketing, and the use of intellectual property including the brand (unlimited access to the use of the Company’s brand and frequent flyer member lists), which is the predominant element in the Agreement. The affinity card bank partner is the customer for some elements, including the brand and marketing, while the Mileage Plan™ member is the customer for other elements such as mileage credits, bag waivers, and companion fares.

At the inception of the Agreement, management estimated the selling price of each of the performance obligations. The objective was to determine the price at which a sale would be transacted if the product or service was sold on a stand-alone basis. The Company determined its best estimate of selling price for each element by considering multiple inputs and methods including, but not limited to, the estimated selling price of comparable travel, discounted cash flows, brand value, published selling prices, number of miles awarded and number of miles redeemed. The Company estimated the selling prices and volumes over the term of the Agreement in order to determine the allocation of proceeds to each of the multiple deliverables. The estimates of the standalone selling prices of each element do not change subsequent to the original valuation of the contract unless the contract is materially modified, but the allocation between elements may change based upon the actual and updated projected volumes of each element delivered during the term of the contract.

Consideration received from the bank is variable and is primarily from consumer spend on the card, among other items. The Company allocates consideration to each of the performance obligations, including mileage credits, waived bag fees, companion fares, and brand and marketing, using their relative standalone selling price. Because the performance obligation related to providing use of intellectual property including the brand is satisfied over time, it is recognized in Mileage Plan^TM other revenue in the period that those elements are sold. The Company records passenger revenue related to the air transportation and certificates for discounted companion travel when the transportation is delivered.

In contracts with non-bank partners, the Company has identified two performance obligations in most cases - travel and brand. Revenue is recognized using the residual method, where the travel performance obligation is deferred until transportation is provided in the amount of the estimated standalone selling price of the ticket, less breakage. The residual amount, if any, is recognized as commission revenue when the brand element is sold. Mileage credit sales recorded under the residual approach are immaterial to the overall program.

Interline loyalty

The Company has interline arrangements with certain airlines whereby its members may earn and redeem Mileage Plan™ credits on those airlines, and members of a partner airline’s loyalty program may earn and redeem frequent flyer program credits on Alaska. When a Mileage Plan™ member earns credits on a partner airline, the partner airline remits a contractually-agreed upon fee to the Company which is deferred until credits are redeemed. When a Mileage Plan™ member redeems credits on a partner airline, the Company pays a contractually agreed upon fee to the other airline, which offsets the revenue recognized associated with the award travel. When a member of a partner airline redeems frequent flyer credits on Alaska, the partner airline remits a contractually-agreed upon amount to the Company, recognized as Passenger revenue upon travel. If the partner airline’s member earns frequent flyer program credits on an Alaska flight, the Company remits a contractually-agreed upon fee to the partner airline and records a commission expense.

Total Mileage Plan™ revenue	$	275	$	252	$	521	$	480

Mileage Plan™ other revenue is primarily brand and marketing revenue from our affinity card products.

Cargo and Other

The Company provides freight and mail services (cargo). The majority of cargo services are provided to commercial businesses and the United States Postal Service. The Company satisfies cargo service performance obligations and recognizes revenue when the shipment arrives at its final destination, or is transferred to a third-party carrier for delivery.

The Company also earns other revenue for lounge memberships, hotel and car commissions, and certain other immaterial items not intrinsically tied to providing air travel to passengers. Revenue is recognized when these services are rendered and recorded as Cargo and other revenue. The transaction price for Cargo and other revenue is the price paid by the customer.

Air Traffic Liability and Deferred Revenue

Passenger ticket and ancillary services liabilities

Air traffic liability included on the condensed consolidated balance sheets represents the remaining obligation associated with passenger tickets and ancillary services. The air traffic liability balance fluctuates with seasonal travel patterns. The Company recognized Passenger revenue of $79 million and $89 million from the prior year-end air traffic liability balance for the three months ended June 30, 2018 and 2017, and $513 million and $520 million for the six months ended June 30, 2018 and 2017.

Mileage Plan^TM liabilities

The total deferred revenue liability included on the condensed consolidated balance sheets represents the remaining transaction price that has been allocated to Mileage Plan^TM performance obligations not yet satisfied by the Company. In general, the current amounts will be recognized as revenue within 12 months and the long-term amounts will be recognized as revenue over, on average, a period of approximately three to four years. This period of time represents the average time that members have historically taken to earn and redeem miles.

The Company records a receivable for amounts due from the affinity card partner and from other partners as mileage credits are sold until the payments are collected. The Company had $103 million of such receivables as of June 30, 2018 and $101 million as of December 31, 2017.

Mileage credits are combined in one homogeneous pool and are not specifically identifiable. As such, loyalty revenues disclosed earlier in this Note are comprised of miles that were part of the deferred revenue and liabilities balances at the beginning of the period and miles that were issued during the period. The table below presents a roll forward of the total frequent flyer liability (in millions):



	Six Months Ended June 30,
	2018			2017
Total Deferred Revenue balance at January 1	$	1,725		$	1,534
Travel miles and companion certificate redemption - Passenger revenue	(306		)	(271		)
Miles redeemed on partner airlines - Other revenue	(44		)	(44		)
Increase in liability for mileage credits issued	402			382
Total Deferred Revenue balance at June 30	$	1,777		$	1,601

Selling Costs

Certain costs such as credit card fees, travel agency and other commissions paid, as well as Global Distribution Systems (GDS) booking fees are incurred when the Company sells passenger tickets and ancillary services in advance of the travel date. The Company defers such costs and recognizes them as expenses when the travel occurs. Prepaid expense recorded on the consolidated balance sheets for such costs was $31 million and $24 million as of June 30, 2018 and December 31, 2017. The Company recorded related expense on the condensed consolidated statement of operations of $58 million and $66 million for the three months ended June 30, 2018 and 2017, and $109 million and $122 million for the six months ended June 30, 2018 and 2017.

NOTE 4. FAIR VALUE MEASUREMENTS

In determining fair value, there is a three-level hierarchy based on the reliability of the inputs used. Level 1 refers to fair values based on quoted prices in active markets for identical assets or liabilities. Level 2 refers to fair values estimated using significant other observable inputs and Level 3 refers to fair values estimated using significant unobservable inputs.

Fair Value of Financial Instruments on a Recurring Basis

As of June 30, 2018, total cost basis for all marketable securities was $1.5 billion. There were no significant differences between the cost basis and fair value of any individual class of marketable securities.

Fair values of financial instruments on the consolidated balance sheet (in millions):

The Company uses both the market and income approach to determine the fair value of marketable securities. U.S. government securities are Level 1 as the fair value is based on quoted prices in active markets. Foreign government bonds, asset-backed securities, mortgage-backed securities, corporate notes and bonds, and municipal securities are Level 2 as the fair value is based on standard valuation models that are calculated based on observable inputs such as quoted interest rates, yield curves, credit ratings of the security and other observable market information.

The Company uses the market approach and the income approach to determine the fair value of derivative instruments. The fair value for fuel hedge call options is determined utilizing an option pricing model based on inputs that are readily available in active markets or can be derived from information available in active markets. In addition, the fair value considers the exposure to credit losses in the event of non-performance by counterparties. Interest rate swap agreements are Level 2 as the fair value of these contracts is determined based on the difference between the fixed interest rate in the agreements and the observable LIBOR-based interest forward rates at period end multiplied by the total notional value.

Activity and Maturities for Marketable Securities

Unrealized losses from marketable securities are primarily attributable to changes in interest rates. Management does not believe any unrealized losses represent other-than-temporary impairments based on its evaluation of available information as of June 30, 2018.

Maturities for marketable securities (in millions):



June 30, 2018	Cost Basis		Fair Value
Due in one year or less	$	263	$	262
Due after one year through five years	1,195		1,173
Due after five years through 10 years	31		31
Total	$	1,489	$	1,466

Fair Value of Other Financial Instruments

The Company uses the following methods and assumptions to determine the fair value of financial instruments that are not recognized at fair value as described below.

Cash, Cash Equivalents and Restricted Cash: Cash equivalents consist of highly liquid investments with original maturities of three months or less, such as money market funds, commercial paper and certificates of deposit. They are carried at cost, which approximates fair value.

The Company's restricted cash balances are primarily used to guarantee various letters of credit, self-insurance programs or other contractual rights. Restricted cash consists of highly liquid securities with original maturities of three months or less. They are carried at cost, which approximates fair value.

Debt: Debt assumed in the acquisition of Virgin America was subject to a non-recurring fair valuation adjustment as part of purchase price accounting. The adjustment is amortized over the life of the associated debt. All other fixed-rate debt is carried at cost. To estimate the fair value of all fixed-rate debt as of June 30, 2018, the Company uses the income approach by discounting cash flows using borrowing rates for comparable debt over the remaining life of the outstanding debt. The estimated fair value of the fixed-rate debt is Level 3 as certain inputs used are unobservable.

Fixed-rate debt on the consolidated balance sheet and the estimated fair value of long-term fixed-rate debt is as follows (in millions):



	June 30, 2018		December 31, 2017
Fixed-rate debt at cost	$	838	$	956
Non-recurring purchase price accounting fair value adjustment	3		3
Total fixed-rate debt	$	841	$	959

Estimated fair value	$	831	$	959

Assets and Liabilities Measured at Fair Value on Nonrecurring Basis

Certain assets and liabilities are recognized or disclosed at fair value on a nonrecurring basis, including property, plant and equipment, goodwill, and intangible assets. These assets are subject to fair valuation when there is evidence of impairment. No impairment was recognized in the three and six months ended June 30, 2018 or June 30, 2017.

NOTE 5. LONG-TERM DEBT

Bank Lines of Credit

The Company had three credit facilities totaling $475 million as of June 30, 2018. All three facilities have variable interest rates based on LIBOR plus a specified margin. One credit facility for $250 million expires in June 2021 and is secured by aircraft. A second credit facility for $75 million expires in September 2018, with a mechanism for annual renewal, and is secured by aircraft. Subsequent to June 30, 2018, we increased this credit facility from $75 million to $116 million and extended the maturity date to July 2019. A third credit facility for $150 million expires in March 2022 and is secured by certain accounts receivable, spare engines, spare parts and ground service equipment. The Company has secured letters of credit against the $75 million facility, but has no plans to borrow using either of the two other facilities. All three credit facilities have a requirement to maintain a minimum unrestricted cash and marketable securities balance of $500 million. The Company was in compliance with this covenant at June 30, 2018.

(a)	Includes non-cancelable contractual commitments for aircraft and engines, buyer furnished equipment, and aircraft maintenance and parts management.


(b)	Includes all non-aircraft lease costs associated with capacity purchase agreements.

Lease Commitments

Aircraft lease commitments include future obligations for all of the Company's operating airlines, as well as aircraft leases operated by third-parties. At June 30, 2018, the Company had lease contracts for 10 Boeing 737 (B737) aircraft, 61 Airbus aircraft, 11 Bombardier Q400 aircraft, and 29 Embraer 175 (E175) with SkyWest Airlines, Inc. (SkyWest). The Company has an additional two scheduled lease deliveries of A321neo aircraft through 2019, as well as six scheduled lease deliveries of E175 aircraft through 2021 to be operated by SkyWest. All lease contracts have remaining non-cancelable lease terms ranging from 2018 to 2033. The Company has the option to increase capacity flown by SkyWest with eight additional E175 aircraft with deliveries in 2020. Options to lease are not reflected in the commitments table above.

Facility lease commitments primarily include airport and terminal facilities and building leases. Total rent expense for aircraft and facility leases was $137 million and $123 million for the three months ended June 30, 2018 and 2017, and $290 million and $261 million for the six months ended June 30, 2018 and 2017.

Aircraft Commitments

Aircraft purchase commitments include non-cancelable contractual commitments for aircraft and engines. As of June 30, 2018, the Company had commitments to purchase 41 B737 aircraft (9 B737 NextGen aircraft and 32 B737 MAX aircraft), with deliveries in the remainder of 2018 through 2023. In the first quarter of 2018 the Company entered into a supplemental agreement with Boeing to defer certain B737 deliveries and to convert 15 MAX8 aircraft orders to MAX9 aircraft orders. The Company also has commitments to purchase 18 E175 aircraft with deliveries in the remainder of 2018 through 2021 and has cancelable purchase commitments for 30 Airbus A320neo aircraft with deliveries from 2021 through 2023. In addition, the Company has options to purchase 37 B737 aircraft and 30 E175 aircraft. The cancelable purchase commitments and option payments are not reflected in the table above.

Contingencies

The Company is a party to routine litigation matters incidental to its business and with respect to which no material liability is expected. Liabilities for litigation related contingencies are recorded when a loss is determined to be probable and estimable.

In 2015, three flight attendants filed a class action lawsuit seeking to represent all Virgin America flight attendants for damages based on alleged violations of California and City of San Francisco wage and hour laws. Plaintiffs received class certification in November 2016. Virgin America filed a motion for summary judgment seeking to dismiss all claims on various federal preemption grounds. In January 2017, the Court denied in part and granted in part Virgin America’s motion. In January 2018, Virgin America filed a motion to decertify the class and Plaintiffs filed a motion for summary judgment seeking the court to rule in their favor on all remaining claims. In July 2018, the Court denied in part and granted in part Virgin America's motion to decertify the class and granted in part and denied in part Plaintiffs' motion for summary judgment. A trial on the remaining claim is currently set for October 2018. The Company believes the claims in this case are without factual and legal merit and intends to defend the remaining claim in this lawsuit and will appeal the claims decided in the Plaintiffs' favor.

Management is currently assessing the potential impact of the July 2018 decision by the Court, and has not yet determined the range of possible outcomes. While management believes the outcome of subsequent appeals will ultimately resolve in favor of the Company's position, damages assessed in the Plaintiffs' favor under the July 2018 ruling could be material. This forward-looking statement is based on management's current understanding of the relevant law and facts, and it is subject to various contingencies, including the potential costs and risks associated with litigation and the actions of arbitrators, judges and juries.

NOTE 8. SHAREHOLDERS' EQUITY

Dividends

During the three months ended June 30, 2018, the Company declared and paid cash dividends of $0.32 per share, or $40 million. During the six months ended June 30, 2018, the Company declared and paid cash dividends of $0.64 per share, or $79 million.

Common Stock Repurchase

In August 2015, the Board of Directors authorized a $1 billion share repurchase program. As of June 30, 2018, the Company has repurchased 5.5 million shares for $413 million under this program.

The Company elected to early adopt ASU 2018-02 in the first quarter of 2018. As a result, the Company reclassified approximately $62 million of tax effects in AOCI recorded in prior periods at previously enacted tax rates thus increasing Retained earnings.

Earnings Per Share (EPS)

Diluted EPS is calculated by dividing net income by the average number of common shares outstanding plus the number of additional common shares that would have been outstanding assuming the exercise of in-the-money stock options and restricted stock units, using the treasury-stock method. For the three and six months ended June 30, 2018 and 2017, anti-dilutive shares excluded from the calculation of EPS were not material.

NOTE 9. OPERATING SEGMENT INFORMATION

Alaska Air Group has two operating airlines—Alaska (including Virgin America after the single operating certificate received in January 2018) and Horizon. Each is regulated by the U.S. Department of Transportation’s Federal Aviation Administration. Alaska has CPAs for regional capacity with Horizon, as well as with third-party carriers SkyWest and PenAir, under which Alaska receives all passenger revenues.

Under U.S. GAAP, operating segments are defined as components of a business for which there is discrete financial information that is regularly assessed by the Chief Operating Decision Maker (CODM) in making resource allocation decisions. Financial performance for the operating airlines and CPAs is managed and reviewed by the Company's CODM as part of three reportable operating segments:


•	Mainline - includes scheduled air transportation on Alaska's Boeing or Airbus jet aircraft for passengers and cargo throughout the U.S., and in parts of Canada, Mexico, and Costa Rica.


•	Regional - includes Horizon's and other third-party carriers’ scheduled air transportation for passengers across a shorter distance network within the U.S. under CPAs. This segment includes the actual revenues and expenses associated with regional flying, as well as an allocation of corporate overhead incurred by Air Group on behalf of the regional operations.


•	Horizon - includes the capacity sold to Alaska under CPA. Expenses include those typically borne by regional airlines such as crew costs, ownership costs and maintenance costs.

The CODM makes resource allocation decisions for these reporting segments based on flight profitability data, aircraft type, route economics and other financial information.

The "Consolidating and Other" column reflects parent company activity, McGee Air Services, consolidating entries and other immaterial business units of the company. The “Air Group Adjusted” column represents a non-GAAP measure that is used by the Company's CODM to evaluate performance and allocate resources. Adjustments are further explained below in reconciling to consolidated GAAP results.

Operating segment information is as follows (in millions):

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) is intended to help the reader understand our company, segment operations and the present business environment. MD&A is provided as a supplement to – and should be read in conjunction with – our consolidated financial statements and the accompanying notes. All statements in the following discussion that are not statements of historical information or descriptions of current accounting policy are forward-looking statements. Please consider our forward-looking statements in light of the risks referred to in this report’s introductory cautionary note and the risks mentioned in "Item 1A. Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2017. This overview summarizes the MD&A, which includes the following sections:


•	Second Quarter Review—highlights from the second quarter of 2018 outlining some of the major events that happened during the period and how they affected our financial performance.

•

Results of Operations—an in-depth analysis of our revenues by segment and our expenses from a consolidated perspective for the three and six months ended June 30, 2018. To the extent material to the understanding of segment profitability, we more fully describe the segment expenses per financial statement line item. Financial and statistical data is also included here. This section includes forward-looking statements regarding our view of the remainder of 2018.


•	Liquidity and Capital Resources—an overview of our financial position, analysis of cash flows, and relevant contractual obligations and commitments.

SECOND QUARTER REVIEW

Our consolidated pretax income was $259 million during the second quarter of 2018, compared to $474 million in the second quarter of 2017. The decrease in pretax income of $215 million was driven largely by an increase in fuel expense of $131 million and an increase in non-fuel operating expenses of $139 million, partially offset by an increase in operating revenues of $54 million.

See “Results of Operations” below for further discussion of changes in revenues and operating expenses and our reconciliation of non-GAAP measures to the most directly comparable GAAP measure.

Operations Performance

During the second quarter of 2018, our on-time performance was 82.5% for Alaska Mainline and 86.4% for our Regional operations. These on-time results are in-line with our historical high standard of running an excellent operation, and an improvement from operational headwinds encountered in 2017.

New Markets

We announced three new routes during the second quarter of 2018. Approximately 88% of projected growth in 2018 is within existing routes and locations, with the rest attributable to our plans to add more routes connecting guests along the West Coast to high demand markets in the lower 48 states and Hawaii.

Shareholder Return

During the second quarter of 2018, we paid cash dividends of $40 million and repurchased 204,078 shares for $13 million.

Labor Update

In July 2018, we ratified a merger transition agreement for dispatchers, represented by the Transport Workers Union (TWU). The agreement brings the Boeing and Airbus dispatch groups together under Alaska’s existing CBA. It includes a two-year extension of the existing contract from 2019 to 2021, provides pay rate increases through the new contract term, and paves the way for an integrated seniority list.

Four of our five unionized groups at Alaska have the merger transition agreements required to fully integrate. This is a major milestone just 19 months after the official close of the acquisition of Virgin America in December 2016. A tentative agreement reached with the Aircraft Mechanics Fraternal Association (AMFA) was rejected by Boeing technicians. We will continue to work with AMFA and our technicians to reach a transition agreement.

Outlook

In 2018 and beyond, we are focused on successfully completing the integration of Virgin America. We have completed two of our most significant integration milestones to date and continue to make progress on our integration. In January 2018, Alaska and Virgin America received a Single Operating Certificate (SOC) from the FAA, which recognizes Alaska and Virgin America as one airline. In April, we transitioned to a single Passenger Service System (PSS), which allows us to provide one reservation system, one website and one inventory of flights to our guests. Our transition to a single PSS allows us to unlock many of the revenue synergies expected from the acquisition, as well as provide consistent branding to our guests at all airports gates, ticketing, and check-in areas.

Additionally, in June, we received FAA approval for our Airbus emergency procedures. This allows us to move forward with transition training for flight attendants so they can work on both Boeing and Airbus aircraft. We also integrated to a single weight and balance system in June. This not only allows us to take cargo on Airbus aircraft, which is an important revenue synergy, but it will also improve operational performance.

With the completion of our most recent milestones, our integration is now approximately 85 percent complete. One of the last major milestones to complete is our Airbus fleet reconfiguration. Between now and the end of 2018, we will paint approximately 25 Airbus aircraft with the Alaska livery and will begin reconfiguring Airbus aircraft to align with the Boeing aircraft to achieve one consistent cabin experience for our guests. We will also be integrating our crew management systems in late 2018 and early 2019.

We continue to make investments to enhance our onboard guest experience. Some of the more notable projects underway include adding satellite connectivity to our entire Boeing and Airbus fleets to offer high-speed satellite Wi-Fi, updating and expanding airport lounges in the JFK and Seattle airports, and investment in our Seattle hub airport to open a state-of-the-art 20-gate North Terminal facility. Throughout 2018 we will also be introducing new food and beverage menus, which include more fresh, local, and healthy offerings with a distinct West Coast vibe including salads, protein plates, and fresh snacks. Beginning in July, all Boeing and Airbus flights will have new beverage offerings, including craft beers, new juices and, coming this fall, an updated wine selection.

In April, we entered into a lease agreement with Southwest for 12 airport slots at LaGuardia Airport (LGA) and eight airport slots at Regan National Airport (DCA). The lease begins October 2018 and continues through 2028. This agreement enables us to monetize these valuable slots, and reallocate flying from Dallas Love Field (DAL) to more strategic and profitable opportunities on the West Coast. We maintain the right to resume flying using these slots, should we choose to do so, in 2028 when the agreement expires.

We have also announced new revenue initiatives. This fall, we will introduce a new option for our guests called the "Saver Fare," a low-priced product which we believe will result in annual revenue of approximately $100 million and is incremental to merger synergies. In addition, we have implemented a series of other revenue initiatives, such as offering exit rows for sale, introducing dynamic pricing for our premium class seats, leveraging new technology to better manage revenue post-sale, and eliminating fee waivers for changes made outside of 60 days. We believe these changes provide guests with more options and reflects the significant increase in the value of our expanded network and product, as well as unlocking the substantial synergies from the merger.

Currently, we expect to grow our combined network capacity by approximately 6% in 2018 and approximately 2% in 2019. Current schedules indicate competitive capacity will increase by approximately 4.5% in the third quarter of 2018, and approximately 6% in the fourth quarter of 2018. We believe that our product, our operation, our engaged employees, our award-winning service, and our competitive Mileage Plan™ program, combined with our strong balance sheet and focus on low costs, give us a competitive advantage in our markets.

Our current expectations for capacity and CASM excluding fuel and special items for the second quarter and full year 2018 are summarized below:



	Forecast Q3 2018	Q3 2017	% Change
Capacity (ASMs in millions)	17,095 - 17,145	16,164	~ 5.9%
Cost per ASM excluding fuel and special items (cents)^(a)	8.36¢ - 8.41¢	8.00¢	~ 4.9%



	Forecast Full Year 2018	Full Year 2017	% Change
Capacity (ASMs in millions)	65,780 - 65,930	62,072	~ 6.1%
Cost per ASM excluding fuel and special items (cents)^(a)	8.50¢ - 8.53¢	8.25¢	~ 3.2%


(a)	2017 CASMex reflects the impacts of the updated accounting standards, effective for the Company January 1, 2018.

RESULTS OF OPERATIONS

ADJUSTED (NON-GAAP) RESULTS AND PER-SHARE AMOUNTS

We believe disclosure of earnings excluding the impact of merger-related costs, mark-to-market gains or losses or other individual special revenues or expenses is useful information to investors because:

•

By excluding fuel expense and certain special items (including merger-related costs) from our unit metrics, we believe that we have better visibility into the results of operations and our non-fuel cost initiatives. Our industry is highly competitive and is characterized by high fixed costs, so even a small reduction in non-fuel operating costs can lead to a significant improvement in operating results. In addition, we believe that all domestic carriers are similarly impacted by changes in jet fuel costs over the long run, so it is important for management (and thus investors) to understand the impact of (and trends in) company-specific cost drivers, such as labor rates and productivity, airport costs, maintenance costs, etc., which are more controllable by management.


•	Cost per ASM (CASM) excluding fuel and certain special items, such as merger-related costs, is one of the most important measures used by management and by the Air Group Board of Directors in assessing quarterly and annual cost performance.


•	Adjusted income before income tax and CASM excluding fuel (and other items as specified in our plan documents) are important metrics for the employee cash incentive plan, which covers the majority of Air Group employees.


•	CASM excluding fuel and certain special items is a measure commonly used by industry analysts and we believe it is an important metric by which they compare our airlines to others in the industry. The measure is also the subject of frequent questions from investors.

•

Disclosure of the individual impact of certain noted items provides investors the ability to measure and monitor performance both with and without these special items. We believe that disclosing the impact of certain items, such as merger-related costs, and mark-to-market hedging adjustments, is important because it provides information on significant items that are not necessarily indicative of future performance. Industry analysts and investors consistently measure our performance without these items for better comparability between periods and among other airlines.

•

Although we disclose our unit revenues, we do not (nor are we able to) evaluate unit revenues excluding the impact that changes in fuel costs have had on ticket prices. Fuel expense represents a large percentage of our total operating expenses. Fluctuations in fuel prices often drive changes in unit revenues in the mid-to-long term. Although we believe it is useful to evaluate non-fuel unit costs for the reasons noted above, we would caution readers of these financial statements not to place undue reliance on unit costs excluding fuel as a measure or predictor of future profitability because of the significant impact of fuel costs on our business.

Although we are presenting these non-GAAP amounts for the reasons above, investors and other readers should not necessarily conclude that these amounts are non-recurring, infrequent, or unusual in nature.

COMPARISON OF THREE MONTHS ENDED JUNE 30, 2018 TO THREE MONTHS ENDED JUNE 30, 2017

Our consolidated net income for the three months ended June 30, 2018 was $193 million, or $1.56 per diluted share, compared to net income of $293 million, or $2.36 per diluted share, for the three months ended June 30, 2017.

Excluding the impact of merger-related costs and mark-to-market fuel hedge adjustments, our adjusted net income for the second quarter of 2018 was $206 million, or $1.66 per diluted share, compared to an adjusted net income of $309 million, or $2.48 per diluted share, in the second quarter of 2017. Historical information has been adjusted to reflect the adoption of new accounting standards effective for the Company January 1, 2018. The following tables reconcile our adjusted net income and adjusted earnings per diluted share (EPS) to amounts as reported in accordance with GAAP:

OPERATING REVENUES

Total operating revenues increased $54 million, or 3%, during the second quarter of 2018 compared to the same period in 2017. The changes are summarized in the following table:



	Three Months Ended June 30,
(in millions)	2018		2017		% Change
Passenger revenue	$	1,997	$	1,945	3	%
Mileage plan other revenue	108		109		(1	)%
Cargo and other	51		48		6	%
Total operating revenues	$	2,156	$	2,102	3	%

Passenger Revenue

On a consolidated basis, Passenger revenue for the second quarter of 2018 increased by $52 million, or 3%, on an 8% increase in capacity, partially offset by 4% lower ticket yields and a 1 pt decrease in load factor. The increase in capacity was driven by our continued network expansion and aircraft added to our fleet since the second quarter of 2017. Lower yields are a result of competitive pricing pressure we are experiencing, specifically on the West Coast, while lower load factor is a result of significant capacity growth in our markets by us and our competitors. We are working on a number of revenue initiatives to help improve our revenue performance.

Mileage Plan™ Other Revenue

On a consolidated basis, Mileage Plan™ other revenue decreased $1 million, or 1%, compared to the second quarter of 2017. The decrease is primarily attributable to higher costs for redemption of awards on other airlines, partially offset by an increase in commission revenue from our growing affinity credit card program.

OPERATING EXPENSES

Total operating expenses increased $270 million, or 17%, compared to the second quarter of 2017. We believe it is useful to summarize operating expenses as follows, which is consistent with the way expenses are reported internally and evaluated by management:



	Three Months Ended June 30,
(in millions)	2018		2017		% Change
Fuel expense	$	475	$	344	38	%
Non-fuel operating expenses, excluding special items	1,371		1,247		10	%
Special items—merger-related costs	39		24		63	%
Total operating expenses	$	1,885	$	1,615	17	%

Fuel Expense

Aircraft fuel expense includes raw fuel expense (as defined below) plus the effect of mark-to-market adjustments to our fuel hedge portfolio as the value of that portfolio increases and decreases. Our aircraft fuel expense can be volatile because it includes these gains or losses in the value of the underlying instrument as crude oil prices and refining margins increase or decrease. Raw fuel expense is defined as the price that we generally pay at the airport, or the “into-plane” price, including taxes and fees. Raw fuel prices are impacted by world oil prices and refining costs, which can vary by region in the U.S. Raw fuel expense approximates cash paid to suppliers and does not reflect the effect of our fuel hedges.

Aircraft fuel expense increased $131 million, or 38%, compared to the second quarter of 2017. The elements of the change are illustrated in the following table:



	Three Months Ended June 30,
	2018						2017
(in millions, except for per gallon amounts)	Dollars			Cost/Gal			Dollars		Cost/Gal
Raw or "into-plane" fuel cost	$	506		$	2.34		$	337	$	1.69
(Gains) losses on settled hedges	(9		)	(0.04		)	5		0.02
Consolidated economic fuel expense	497			2.30			$	342	$	1.71
Mark-to-market fuel hedge adjustments	(22		)	(0.10		)	2		0.01
GAAP fuel expense	$	475		$	2.20		$	344	$	1.72
Fuel gallons	216						201

Raw fuel expense per gallon for the three months ended June 30, 2018 increased by approximately 38% due to higher West Coast jet fuel prices. West Coast jet fuel prices are impacted by both the price of crude oil, and refining margins associated with the conversion of crude oil to jet fuel. The increase in raw fuel price per gallon during the second quarter of 2018 was primarily driven by a 57% increase in refining margins and a 41% increase in crude oil prices, when compared to the prior year. Fuel gallons consumed increased by 15 million gallons, or 7%, in line with the increase in capacity.

We also evaluate economic fuel expense, which we define as raw fuel expense adjusted for the cash we receive from, or pay to, hedge counterparties for hedges that settle during the period, and for the premium expense that we paid for those contracts. A key difference between aircraft fuel expense and economic fuel expense is the timing of gain or loss recognition on our hedge portfolio. When we refer to economic fuel expense, we include gains and losses only when they are realized for those contracts that were settled during the period based on their original contract terms. We believe this is the best measure of the effect that fuel prices are currently having on our business because it most closely approximates the net cash outflow associated with purchasing fuel for our operations. Accordingly, many industry analysts evaluate our results using this measure, and it is the basis for most internal management reporting and incentive pay plans.

Gains recognized for hedges that settled during the second quarter were $9 million in 2018, compared to losses of $5 million in the same period in 2017. These amounts represent cash paid for premium expense, offset by any cash received from those hedges at settlement.

Non-fuel Expenses

The table below provides the reconciliation of the operating expense line items, excluding fuel and special items. Significant operating expense variances from 2017 are more fully described below.

Wages and Benefits

Wages and benefits increased during the second quarter of 2018 by $74 million, or 16%. The primary components of Wages and benefits are shown in the following table:



	Three Months Ended June 30,
(in millions)	2018		2017		% Change
Wages	$	411	$	359	14	%
Pension—Defined benefit plans service cost	12		10		20	%
Defined contribution plans	30		23		30	%
Medical and other benefits	61		52		17	%
Payroll taxes	30		26		15	%
Total wages and benefits	$	544	$	470	16	%

Wages increased 14% on a 10% increase in FTEs. The increase in FTEs is primarily attributable to the growth in McGee Air Services, which has insourced certain airport group service functions that were previously provided by third-party vendors and reflected in Contracted Services expense. To a lesser extent, we have experienced FTE growth in other areas as the business has grown. The remaining increase in wages is driven by increased wage rates in many work groups, including pilots and flight attendants whose new contract rates became effective in the fourth quarter of 2017 and first quarter of 2018, respectively.

Variable Incentive Pay

Variable incentive pay expense increased by $11 million, or 41%, during the second quarter of 2018 compared to the same period in 2017. This increase was primarily due to a higher wage base on which performance-based pay is determined.

Aircraft Maintenance

Aircraft maintenance expense increased by $10 million, or 10%, during the second quarter of 2018 compared to the same period in 2017. Maintenance costs increased primarily due to a power-by-the-hour engine maintenance arrangement on our B737-800 aircraft which was entered into, and became effective, in the fourth quarter of 2017. Although the agreement results in increased expense earlier in the engine life cycle of B737-800 aircraft, it allows for much more predictable expense patterns over the fleet life.

Landing Fees and Other Rentals

Landing fees and other rental expenses increased by $11 million, or 11%, during the second quarter of 2018 compared to the same period in 2017. This increase was primarily driven by our 8% increase in capacity and rate increases at airports across our network.

Selling Expenses

Selling expenses decreased $14 million, or 14%, during the second quarter of 2018 compared to the same period in 2017. This decrease was primarily due to decreased commission costs from other airlines for transporting their frequent flyer members, lower credit card commissions, and decreased promotional and advertising activities, specifically those related to Virgin America.

Third-party regional carrier expense

Third-party regional carrier expense, which represents payments made to SkyWest and PenAir under our CPA agreements, increased by $12 million, or 44%, during the second quarter of 2018 compared to the same period in 2017. This increase is primarily due to the additional nine E175 aircraft operated by SkyWest compared to the second quarter of 2017.

Special Items – Merger-related Costs

We recorded special items of $39 million for merger-related costs associated with our acquisition of Virgin America during the second quarter of 2018, compared to $24 million during the same period in 2017. Costs incurred in the second quarter of 2018 consisted primarily of IT integration costs as well as the write off of Virgin America related assets connected with our transition to a single PSS in April. We expect to continue to incur merger-related costs through 2019.

ADDITIONAL SEGMENT INFORMATION

Refer to Note 9 of the consolidated financial statements for a detailed description of each segment. Below is a summary of each segment's profitability.

Mainline

Mainline recorded pretax profit of $288 million in the second quarter of 2018, compared to $478 million in the second quarter of 2017. The $190 million decrease in pretax profit was primarily driven by a $128 million increase in economic fuel cost and a $105 million increase in non-fuel operating expenses, partially offset by a $34 million increase in passenger revenues.

The increase in Mainline passenger revenue for the second quarter of 2018 was primarily driven by capacity growth, partially offset by lower average fares.

Higher raw fuel prices and an increase in gallons consumed to support additional flying drove the increase in Mainline fuel expense. Non-fuel operating expenses increased due to higher wages to support our growth, and higher operating expenses as described above.

Regional

Our Regional operations incurred a pretax loss of $20 million in the second quarter of 2018, compared to a pretax profit of $34 million in the second quarter of 2017. The pretax loss was attributable to higher fuel costs, and higher non-fuel operating expense, partially offset by an $18 million increase in operating revenues.

Regional passenger revenue increased 7% compared to the second quarter of 2017, primarily driven by a 22% increase in capacity and an increase in load factor of 0.7 pts, partially offset by 13% lower ticket yields. The increase in capacity is due to an increase in departures from new E175 deliveries, an increase in average aircraft stage length, and the annualization of new routes introduced over the past 12 months. Lower yields are a result of competitive pricing pressure we are experiencing, specifically on the West Coast.

Horizon

Horizon achieved a pretax profit of $10 million in the second quarter of 2018, compared to a pretax loss of $9 million in the second quarter of 2017. The change was primarily driven by a $29 million increase in operating revenue, attributable to the additional nine E175 aircraft added to Horizon's fleet since the second quarter of 2017 and better operating performance in 2018.

COMPARISON OF SIX MONTHS ENDED JUNE 30, 2018 TO SIX MONTHS ENDED JUNE 30, 2017

Our consolidated net income for the six months ended June 30, 2018 was $197 million, or $1.59 per diluted share, compared to net income of $386 million, or $3.10 per diluted share, for the six months ended June 30, 2017.

Excluding the impact of merger-related costs, mark-to-market fuel hedge adjustments, and a special employee tax reform bonus in connection with the passing of the Tax Cuts and Jobs Act (TCJA), our adjusted net income for the six months ended June 30, 2018 was $224 million, or $1.81 per diluted share, compared to an adjusted net income of $433 million, or $3.48 per diluted share, in the six months ended June 30, 2017. Historical information has been adjusted to reflect the adoption of new accounting standards effective for the Company as of January 1, 2018. The following tables reconcile our adjusted net income and adjusted earnings per diluted share (EPS) to amounts as reported in accordance with GAAP:

OPERATING REVENUES

Total operating revenues increased $146 million, or 4%, during the first six months of 2018 compared to the same period in 2017. The changes are summarized in the following table:



	Six Months Ended June 30,
(in millions)	2018		2017		% Change
Passenger revenue	$	3,682	$	3,547	4	%
Mileage plan other revenue	215		209		3	%
Cargo and other	91		86		6	%
Total operating revenues	$	3,988	$	3,842	4	%

Passenger Revenue

On a consolidated basis, Passenger revenue for the first six months of 2018 increased by $135 million, or 4%, on an 8% increase in capacity, partially offset by 2.5% lower ticket yields and a 1 pt decrease in load factor. The increase in capacity was driven by our continued network expansion and aircraft added to our fleet since June 30, 2017. Lower yields are a result of competitive pricing pressure we are experiencing, specifically on the West Coast, while lower load factor is a result of significant capacity growth in our markets by us and our competitors. We are working on a number of revenue initiatives to help improve our revenue performance.

Mileage Plan™ Other Revenue

On a consolidated basis, Mileage Plan™ other revenue increased $6 million or 3% in the first six months of 2018 compared to the first six months of 2017. The increase is primarily attributable to an increase in commission revenue from our growing affinity credit card program, partially offset by increasing costs for redemption of awards on other airlines.

OPERATING EXPENSES

Total operating expenses increased $490 million, or 15%, compared to the first six months of 2017. We believe it is useful to summarize operating expenses as follows, which is consistent with the way expenses are reported internally and evaluated by management:



	Six Months Ended June 30,
(in millions)	2018		2017		% Change
Fuel expense	$	884	$	683	29	%
Non-fuel operating expenses, excluding special items	2,734		2,452		12	%
Special items—merger-related costs	45		63		(29	)%
Special items—employee tax reform bonus	25		—		NM
Total operating expenses	$	3,688	$	3,198	15	%

Fuel Expense

Aircraft fuel expense increased $201 million, or 29%, compared to the six months ended June 30, 2017. The elements of the change are illustrated in the following table:



	Six Months Ended June 30,
	2018						2017
(in millions, except for per gallon amounts)	Dollars			Cost/Gal			Dollars		Cost/Gal
Raw or "into-plane" fuel cost	$	929		$	2.25		$	663	$	1.73
(Gains) losses on settled hedges	(10		)	(0.03		)	8		0.02
Consolidated economic fuel expense	919			2.22			$	671	$	1.75
Mark-to-market fuel hedge adjustments	(35		)	(0.08		)	12		0.03
GAAP fuel expense	$	884		$	2.14		$	683	$	1.78
Fuel gallons	413						385

The raw fuel price per gallon increased 30% due to higher West Coast jet fuel prices. West Coast jet fuel prices are impacted by both the price of crude oil, as well as refining margins associated with the conversion of crude oil to jet fuel. The increase in raw fuel price per gallon during the first six months of 2018 was driven by a 31% increase in crude oil prices and a 53% increase in refining margins.

Gains recognized for hedges that settled in the first six months of 2018 were $10 million, compared to losses of $8 million in the same period in 2017. These amounts represent cash paid for premium expense, offset by cash received from settled hedges.

We currently expect our economic fuel price per gallon to be higher in the third quarter of 2018 compared to the third quarter of 2017 due to our current estimate of higher crude prices and higher refining margins.

Non-fuel Expense and Non- special items



	Six Months Ended June 30,
(in millions)	2018		2017		% Change
Wages and benefits	$	1,080	$	920	17	%

Wages and Benefits

Wages and benefits increased during the first six months of 2018 by $160 million, or 17%, compared to 2017. The primary components of wages and benefits are shown in the following table:



	Six Months Ended June 30,
(in millions)	2018		2017		% Change
Wages	$	818	$	696	18	%
Pension—Defined benefit plans service cost	24		20		20	%
Defined contribution plans	58		48		21	%
Medical and other benefits	121		104		16	%
Payroll taxes	59		52		13	%
Total wages and benefits	$	1,080	$	920	17	%

Wages increased $122 million, or 18%, on a 12% increase in FTEs. The increase in FTEs is primarily attributable to the growth in McGee Air Services, which has insourced certain airport ground service functions that were previously provided by third-party vendors and reflected in Contracted services expense. Additionally, higher wage rates for Boeing and Airbus pilots and flight attendants as a result of new contract rates effective in the fourth quarter or 2017 and the first quarter of 2018, respectively, resulted in higher wages in the current year.

Costs associated with our defined contribution plans increased $10 million, or 21%, due to FTE growth, increased participation throughout all labor groups, and higher contribution rates for Boeing and Airbus pilots and flight attendants as a result of new contract rates effective in the fourth quarter of 2017 and the first quarter of 2018, respectively.

Medical and other benefits expense increased $17 million, or 16%, primarily due to FTE growth and rising medical costs.

For the full year, we expect wages and benefits to increase at a rate greater than capacity growth, due to higher wage rates for certain labor groups and the continued growth of McGee Air Services.

Variable Incentive Pay

Variable incentive pay expense increased during the first six months of 2018 by $19 million, or 33% compared to the same period in 2017. This increase was primarily due to a higher wage base as a result of higher wages noted above.

For the full year, we expect variable incentive pay expense to be higher than in 2017 due to a higher wage base resulting from the new wage rates effective over the past year, particularly for pilots and flight attendants.

Aircraft Maintenance

Aircraft maintenance expense increased by $30 million, or 16%, during the first six months of 2018 compared to the same period in 2017. Maintenance costs increased primarily due to a power-by-the-hour engine maintenance arrangement on our B737-800 aircraft that we entered into, and became effective, in the fourth quarter of 2017.

For the full year, we expect aircraft maintenance expense to increase at a greater rate than capacity growth in 2018.

Aircraft Rent

Aircraft rent expense increased by $17 million, or 13%, during the first six months of 2018 compared to the same period in 2017. Aircraft rent increased primarily due to the addition of six A321neos added to our mainline fleet and nine E175s added to our regional fleet since June 30, 2017, partially offset by the return of four Q400 and four B737-400 aircraft.

For the full year, we expect aircraft rent to increase at a greater rate than capacity due to additional leased A321neo and E175 aircraft added to our fleet in 2018.

Landing Fees and Other Rentals

Landing fees and other rental expenses increased by $22 million, or 10%, during the first six months of 2018 compared to the same period in 2017. This increase was primarily driven by our capacity increase of 8% and rate increases at airports across our network.

For the full year, we expect landing fees and other rental expense to grow at a greater rate than projected capacity growth, due to anticipated rate increases at airports across our network.

Selling Expenses

Selling expenses decreased $19 million, or 10%, during the first six months of 2018 compared to the same period in 2017. This decrease was primarily due to decreased commission costs from other airlines for transporting their frequent flyer members, lower credit card commissions, and decreased promotional and advertising activities, specifically those related to Virgin America.

For the full year, we expect selling expenses to be lower than in 2017 for the reasons mentioned above.

Food and Beverage Service

Food and beverage expense increased $10 million, or 11%, during the first six months of 2018 compared to the same period in 2017. This increase was primarily due to enhancements to our onboard menu offerings to provide higher quality food and beverage products, the addition of premium class offerings, and increased number of passengers.

For the full year, we expect food and beverage expense to increase at a rate consistent with our projected capacity growth.

Third-Party Regional Carrier Expense

Third-party regional carrier expense, which represents payments made to SkyWest and Pen Air under our CPAs, increased $22 million, or 41%, during the first six months of 2018 compared to the same period in 2017. The increase is primarily due to the additional nine E175 aircraft operated by SkyWest in the current year.

For the full year, we expect third-party regional carrier expense to increase at a greater rate than our consolidated capacity growth due to increased flying by our regional partners.

Special Items—Merger-Related Costs

We recorded special items of $45 million for merger-related costs associated with our acquisition of Virgin America in the first six months of 2018, compared to $63 million in the first six months of 2017. Costs incurred in the first six months of 2018 consisted primarily of severance and retention costs, IT integration costs, and the write off of Virgin America related assets connected with our transition to a single PSS in April. We expect to incur merger-related costs for the remainder of 2018, and continuing through 2019.

ADDITIONAL SEGMENT INFORMATION

Refer to Note 9 of the condensed consolidated financial statements for a detailed description of each segment. Below is a summary of each segment's profitability.

Mainline

Mainline adjusted pretax profit was $357 million in the first six months of 2018, compared to $677 million in the same period in 2017. The $320 million decrease in pretax profit was primarily driven by a $236 million increase in Mainline non-fuel operating expenses and a $203 million increase in Mainline fuel expense. These increases were partially offset by a $111 million increase in Mainline passenger revenue.

Non-fuel operating expenses increased on higher wages related to new contract wage rates for pilots and flight attendants, and higher other operating expense categories as described above. Higher raw fuel prices and an increase in gallons consumed drove an increase in Mainline fuel expense. Mainline revenue increased primarily due to increased revenue passengers on lower average fares.

Regional

Our Regional operations incurred a pretax loss of $69 million in the first six months of 2018, compared to a pretax profit of $32 million in the first six months of 2017. The pretax loss was attributable to higher raw fuel costs and higher non-fuel operating expense, partially offset by a $34 million increase in operating revenues.

Horizon

Horizon contributed a pretax profit of $13 million in the first six months of 2018, compared to pretax loss of $16 million in the same period in 2017. The change was primarily driven by a $42 million increase in operating revenue, attributable to the addition of nine E175 aircraft added to Horizon's fleet over the past twelve months.

LIQUIDITY AND CAPITAL RESOURCES

Our primary sources of liquidity are:


•	Our existing cash and marketable securities balance of $1.6 billion, and our expected cash from operations;


•	Our 83 unencumbered operating aircraft that could be financed, if necessary;


•	Our combined bank line-of-credit facilities, with no outstanding borrowings, of $400 million. Information about these facilities can be found in Note 5 to the condensed consolidated financial statements.

During the six months ended June 30, 2018, we took free and clear delivery of three B737-900ER aircraft and five E175 aircraft. We made debt payments totaling $258 million, including the prepayment of $43 million of debt, and paid dividends totaling $79 million.

The table below presents the major indicators of financial condition and liquidity:

The following discussion summarizes the primary drivers of the increase in our cash and marketable securities balance and our expectation of future cash requirements.

ANALYSIS OF OUR CASH FLOWS

Cash Provided by Operating Activities

For the first six months of 2018, net cash provided by operating activities was $726 million, compared to $1,084 million during the same period in 2017. The $358 million decrease in our operating cash flows is primarily attributable to a decrease in net income, driven by rising fuel prices, higher non-fuel operating costs, significant new market development, and continuing competitive pressures. Additionally, we had a smaller year-over-year increase in air traffic liability due to changes in sales patterns and an overall decline in fares, partially offset by capacity growth.

We typically generate positive cash flows from operations and expect to use that cash flow to purchase aircraft and capital equipment, make scheduled debt payments, and return capital to shareholders.

Cash Used in Investing Activities

Cash used in investing activities was $468 million during the first six months of 2018, compared to $971 million during the same period of 2017. Our capital expenditures were $423 million in the first six months of 2018, a decrease of $89 million compared to the six months ended June 30, 2017. This is primarily driven by lower spend on other property and equipment compared to the same period of 2017. Our net purchases of marketable securities decreased by $414 million from the prior year, which is generally timing related. Internally, we analyze our cash and marketable securities balance in the aggregate.

The table below reflects our full-year expectation for capital expenditures based on our current intentions. It does not reflect our actual contractual obligations at this time, nor does it reflect the capital expenditures that would be incurred if we exercised options that are available to us. We have options to acquire 37 B737 aircraft with deliveries from 2020 through 2024, and options to acquire 30 E175 aircraft with deliveries in 2021 to 2023. Options will be exercised only if we believe return on invested capital targets can be met. The table below excludes any associated capitalized interest.



(in millions)	2018		2019		2020
Targeted capital expenditures	$	1,000	$	750	$	750

Cash Used in Financing Activities

Cash used in financing activities was $347 million during the first six months of 2018 compared to $243 million during the same period in 2017. During the first six months of 2018 we made debt payments of $258 million, including the prepayment of $43 million of debt, dividend payments totaling $79 million, and had $25 million in common stock repurchases.

CONTRACTUAL OBLIGATIONS AND COMMITMENTS

Aircraft Commitments

As of June 30, 2018, we have firm orders to purchase or lease 67 aircraft. We also have cancelable purchase commitments for 30 Airbus A320neo with deliveries from 2021 through 2023. We could incur a loss of pre-delivery payments and credits as a cancellation fee. We also have options to acquire 37 B737 aircraft with deliveries from 2020 through 2024 and 30 E175 aircraft with deliveries from 2021 through 2023. In addition to the 29 E175 aircraft currently operated by SkyWest in our regional fleet, we have firm orders to lease six E175 aircraft with deliveries in 2018 through 2021, and options in future periods to add regional capacity by having SkyWest operate up to eight more E175 aircraft.

The following table summarizes expected fleet activity by year as of June 30, 2018:



	Actual Fleet	Expected Fleet Activity^(a)
Aircraft	June 30, 2018	2018 Additions	2018 Removals		December 31, 2018	2019 Changes		December 31, 2019

Total Regional Fleet	89	14	(8	)	95	(3	)	92
Total	317	19	(8	)	328	5		333


(a)	The expected fleet counts at December 31, 2018 and 2019 are subject to change.


(b)	Aircraft are either owned or leased by Horizon or operated under capacity purchase agreement with a third party.


(c)	Aircraft deliveries reflect the supplemental agreement entered with Boeing in the first quarter of 2018 which deferred certain B737 deliveries. Our first MAX9 delivery is scheduled for 2019.

For future firm orders and option exercises, we may finance the aircraft through cash flow from operations, long-term debt, or lease arrangements.

Fuel Hedge Positions

All of our future oil positions are call options, which are designed to effectively cap the cost of the crude oil component of our jet fuel purchases. With call options, we are hedged against volatile crude oil price increases. During a period of decline in crude oil prices, we only forfeit cash previously paid for hedge premiums. Our crude oil positions are as follows:



	Approximate % of Expected Fuel Requirements		Weighted-Average Crude Oil Price per Barrel		Average Premium Cost per Barrel

Credit Card Agreements

We have agreements with a number of credit card companies to process the sale of tickets and other services. Under these agreements, there are material adverse change clauses that, if triggered, could result in the credit card companies holding back a reserve from our credit card receivables. Under one such agreement, we could be required to maintain a reserve if our credit rating is downgraded to or below a rating specified by the agreement or our cash and marketable securities balance fell below $500 million. Under another such agreement, we could be required to maintain a reserve if our cash and marketable securities balance fell below $500 million. We are not currently required to maintain any reserve under these agreements, but if we were, our financial position and liquidity could be materially harmed.

Deferred Income Taxes

For federal income tax purposes, the majority of our assets are fully depreciated over a seven-year life using an accelerated depreciation method or bonus depreciation, if available. For financial reporting purposes, the majority of our assets are depreciated over 15 to 25 years to an estimated salvage value using the straight-line basis. This difference has created a significant deferred tax liability. At some point in the future the depreciation basis will reverse, potentially resulting in an increase in income taxes paid.

While it is possible that we could have material cash obligations for this deferred liability at some point in the future, we cannot estimate the timing of long-term cash flows with reasonable accuracy. Taxable income and cash taxes payable in the short-term are impacted by many items, including the amount of book income generated (which can be volatile depending on revenue and fuel prices), usage of net operating losses, whether "bonus depreciation" provisions are available, any future tax reform efforts at the federal level, as well as other legislative changes that are beyond our control. We believe that we will have the liquidity available to make our future tax payments.

CRITICAL ACCOUNTING ESTIMATES

With the exception of the items noted below, there have been no material changes to our critical accounting estimates for the six months ended June 30, 2018. For information on our critical accounting estimates, see Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" of our Annual Report on Form 10-K for the year ended December 31, 2017.

Frequent Flyer Programs

Alaska's Mileage Plan^TM loyalty program awards mileage credits to members who fly on our airlines and our airline partners, referred to as flown miles. We also sell services, including miles for transportation, Companion Fare^TM certificates, bag fee waivers, and access to our brand and customer lists to a major bank that offers Alaska affinity credit cards. To a lesser extent, miles for transportation are also sold to other non-airline partners, such as hotels and car rental agencies. The outstanding miles may be redeemed for travel on our airlines or any of our airline partners. As long as Mileage Plan^TM is in existence, we have an obligation to provide this future travel.

Mileage credits and the various other services we sell under our loyalty program represent performance obligations that are part of a multiple deliverable revenue arrangement. Accounting guidance requires that we use a relative standalone selling price allocation to allocate consideration received to the material performance obligations in these contracts. Our relative standalone selling price allocation models are refreshed when contracts originate or are materially modified.

At June 30, 2018 we had approximately 229 billion miles outstanding, resulting in an aggregate deferred revenue balance of $1.8 billion. The deferred revenue resulting from our relative selling price allocations requires significant management judgment. There are uncertainties inherent in these estimates. Therefore, different assumptions could affect the amount and/or timing of revenue recognition. The most significant assumptions are described below.


1.	The rate at which we defer sales proceeds related to services sold:

We estimate the standalone selling price for each performance obligation, including mileage credits, by considering multiple inputs and methods, including but not limited to, the estimated selling price of comparable travel, discounted cash flows, brand value published selling prices, number of miles awarded and the number of miles redeemed. We estimate the selling prices and volumes over the terms of the agreements in order to determine the allocation of proceeds to each of the multiple deliverables.


2.	The number of miles that will not be redeemed for travel (breakage):

We estimate how many miles will be used per award. For example, our members may redeem mileage credits for award travel to various locations or choose between a highly restricted award and an unrestricted award. Our estimates are based on the current requirements in our Mileage Plan^TM program and historical award redemption patterns.

We regularly review significant Mileage Plan^TM assumptions and change our assumptions if facts and circumstances indicate that a change is necessary. Any such change in assumptions could have a significant effect on our financial position and results of operations.

GLOSSARY OF AIRLINE TERMS

CASM - operating costs per ASM, or "unit cost"; represents all operating expenses including fuel and special items

CASMex - operating costs excluding fuel and special items per ASM; this metric is used to help track progress toward reduction of non-fuel operating costs since fuel is largely out of our control

Debt-to-capitalization ratio - represents adjusted debt (long-term debt plus the present value of future operating lease payments) divided by total equity plus adjusted debt

Diluted Earnings per Share - represents earnings per share (EPS) using fully diluted shares outstanding

Diluted Shares - represents the total number of shares that would be outstanding if all possible sources of conversion, such as stock options, were exercised

Economic Fuel - best estimate of the cash cost of fuel, net of the impact of settled fuel-hedging contracts in the period

Free Cash Flow - total operating cash flow generated less cash paid for capital expenditures

Load Factor - RPMs as a percentage of ASMs; represents the number of available seats that were filled with paying passengers

Mainline - represents flying Boeing 737 and Airbus 320 family jets and all associated revenues and costs
